$2.69 a gallon

It was 14.18 gallons for just over $38!! That was the first tank of diesel we put in O.P. (optimus prime). The free tank from the dealership took us 478 miles! When I do the math, that is only 33.779971 mpg, which makes me sad, but hey $2.69 is a heck of a lot better than the $3.60 we would have had to pay for the premium in the passat. $3.60 for 15 gallons would have been $54, and easy savings of $16. That does not outweight the extra $55 a month in cary payments, but its cool.
